We had a great start to our Atomic Model presentations last week. We will finish our presentations on Monday and discuss the Atomic Structure test for Tuesday. On Wednesday we will begin our next unit, Chemical Bonds and Reactions. Mr. Biggers (the other science teacher) and I are excited to announce our participation in the Invent Idaho/Science Fair Project. Students will have a choice between creating an Invent Idaho project or conventional science fair project. We will devoting each Friday this winter to this project to prepare for our school Invent Idaho/Science Fair which is scheduled for the 2nd week of February. The top Invent Idaho entries will then proceed for an overnight trip to Boise for Southwest Idaho Regional competition on February 19-20. I'll discuss this in detail in class. So the homework for this week consists of the following:
Thursday, Oct. 22: Recall the atomic model you built last week. Using complete sentences answer the following:
- Make a drawing of your atom. Is your atom a metal, transition metal, (both of which are conductors of electricity), semi-metal (also called semiconductors), non-metal (also called nonconductors), halogen, or noble gas?
- Looking at the valence electrons, does your atom tend to lose or gain electrons? Is it highly reactive, somewhat reactive, or nonreactice?
- Name at least 2 compounds that can be formed by this atom (unless you have a noble gas),
-Have a great week,
-Mr. Pfiester
